Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide color photographic light-sensitive material, and more particularly to a silver halide color photographic light-sensitive material having improved sharpness and non-coloring of white background.

[0002]

2. Description of the Related Art In silver halide color photographic light-sensitive materials used for appreciation, recording and storage of dye images, demands for higher image quality and improved rapid processability are increasing year by year. As a method of improving the image quality of silver halide color photographic light-sensitive materials, photographic couplers having excellent spectral absorption characteristics of the coloring dyes obtained by improving the sharpness by adding antihalation and anti-irradiation dyes and reducing the coating amount of gelatin. Is used to improve color reproducibility, and further, to eliminate unnecessary coloring due to residual color of a dye or the like on the support and the hydrophilic layer coated thereon. Now, as a method for improving the sharpness necessary for improving the image quality in silver halide color photographic light-sensitive materials, dyes for preventing each of halation and irradiation are usually effectively used. The dye used for such a purpose has the following performances: (1) In order not to leave harmful coloring on the photographic light-sensitive material,
It should be completely decolorized during the photographic processing process or be easily eluted from the photographic light-sensitive material. (2) The silver halide emulsion layer in the light-sensitive material should not be chemically adversely affected, for example, sensitivity change or fogging should not occur. (3) It has an appropriate spectral absorption according to the purpose of use. Etc. are needed.

Many efforts have been made by those skilled in the art to find a photographic dye satisfying all the above-mentioned conditions, and the oxonol dye and other azo dyes described in US Pat. No. 4,078,933 and the like are used. Examples thereof include dyes, anthraquinone dyes, arylidene dyes, styryl dyes, triarylmethane dyes, merocyanine dyes and cyanine dyes. Since these dyes are generally water-soluble, they diffuse into all layers in the light-sensitive material. Therefore, in order to improve the sharpness of the intended dye image, it is necessary to add a large amount of dye corresponding to the amount of the dye diffused to other layers. In this case, it is easily expected that the white background will be further colored due to the residual color of the dye, taking into consideration the fact that the speeding up of photographic processing is further advanced as in recent years. By reducing the addition amount of the dye, the above white background coloring is reduced, but the sharpness is decreased, which is contrary to the high image quality of the silver halide color photographic light-sensitive material. .
Therefore, some methods for selectively coloring a specific hydrophilic colloid layer have been proposed, as opposed to the method using a water-soluble dye that diffuses in all layers as described above. For example, JP-A-50-65230 discloses a method in which a hydrophilic polymer containing a portion having a charge opposite to that of a dye ion coexists as a mordant in a hydrophilic colloid layer in order to prevent the diffusion of the dye. . However, although these methods are effective in preventing the diffusion of dye molecules, they tend to adversely affect the elution rate of the dye during photographic processing.

Further, a means for retaining a dye in a specific hydrophilic colloid layer in a solid dispersion state is disclosed in JP-A-56-12639.

No. 1 and WO88-04794. However, also in this case, it was found that the elution rate of the dye during photographic processing was deteriorated by adding the dye dispersion necessary for improving the sharpness. Also in this case, by reducing the amount of the dye added, the dissolution rate is improved, but the sharpness is deteriorated. This is also against the high image quality of the silver halide color photographic light-sensitive material. As another means for improving the sharpness, a method of containing fine colloidal silver in a specific non-photosensitive hydrophilic colloid layer, and titanium oxide in a water-resistant resin coated on a reflective support substrate according to EP 337490A. A method of containing a large amount of particles is known. However, it is necessary to add a large amount of colloidal silver and a white pigment in order to sufficiently improve the sharpness by any of these methods by any of these methods. It was further found that Thus, no technology has been found that satisfies all performances for improving image quality.

As the solid fine particle dye, those which are substantially water-insoluble at least at pH 6 or less and which are substantially water-soluble at pH 8 or more are preferable. The phrase "the dye is substantially water-insoluble at least at pH 6 or less" means that the fine powder dispersion state is insoluble enough to be retained in a hydrophilic colloid having pH 6 or less, for example, an aqueous gelatin solution. A dye having a solubility in water of pH 6 at room temperature (24 ° C.) of 10% by weight or less, and more preferably 5% by weight or less is preferable. Further, “substantially water-soluble at pH 8 or higher” means that the dye is dissolved to such an extent that the fine powder dispersion state cannot be retained in an aqueous solution of at least pH 8 or higher, and more specifically, at pH 8 or higher. Dyes having a solubility in water at room temperature of more than 90% by weight, more preferably more than 95% by weight, are preferred.

It is preferably coated downwardly adjacent to the photosensitive layer. As used herein, "coating adjacent to a layer below" means coating on the side of the support relative to the layer, and the layer is coated via another hydrophilic colloid layer. It can also include a mode. More specifically, "coating below the light-sensitive silver halide emulsion layer" means that a thin non-light-sensitive hydrophilic colloid layer (a coupler or the like may be added) is added to this emulsion layer. It also includes a mode in which a hydrophilic colloid layer containing the compound represented by the general formula (Sa) is applied, but preferably the compound represented by the general formula (Sa) is contained without such a layer. It is preferable that the hydrophilic colloid layer is coated directly below the photosensitive layer.

Examples thereof include gelatin derivatives, graft polymers of gelatin and other polymers, proteins such as albumin and casein, cellulose derivatives (eg, hydroxyethyl cellulose, carboxymethyl cellulose and cellulose sulfate), sodium alginate and starch derivatives. Examples thereof include a wide range of synthetic polymers such as sugars, polyvinyl alcohol, partial acetals of polyvinyl alcohol, poly (N-vinylpyrrolidone), polyacrylic acid, polymethacrylic acid, polyacrylamide, polyvinylimidazole and polyvinylpyrazole.

As the binder or protective colloid that can be used in the light-sensitive material of the present invention, it is advantageous to use gelatin, but other hydrophilic colloids can be used alone or together with gelatin. As a preferable gelatin, it is preferable to use low calcium gelatin having a calcium content of 800 ppm or less, more preferably 200 ppm or less. Further, in order to prevent various molds and bacteria which propagate in the hydrophilic colloid layer and deteriorate the image, it is preferable to add an antifungal agent as described in JP-A-63-271247. In the first and second aspects of the present invention, the total amount of gelatin in the photographic constituent layers is 8.5.
g / m ² or less, preferably 8.0 g / m ² or less, and more preferably 7.5 g / m ² or less. The lower limit of the total amount of gelatin is not particularly limited, but is 5.0 to prevent the oil from seeping out in the photographic constituent layers.

In general color photographic paper, color reproduction by the subtractive method can be performed by including a color coupler which forms a dye having a complementary color relationship with the light to which the silver halide emulsion is exposed. In a general color photographic paper, silver halide emulsion grains are spectrally sensitized by the blue-sensitive, green-sensitive and red-sensitive spectral sensitizing dyes in the order of the color forming layers described above, and are also formed on the support in the order described above.

In order to obtain high sensitivity, it is advantageous to use either of the latter two rather than the particles having a uniform structure, and it is also preferable from the viewpoint of pressure resistance. When the silver halide grains have the structure as described above, the boundary between different portions in the halogen composition is an unclear boundary because a mixed crystal is formed due to the composition difference even if the boundary is clear. Alternatively, it may be one that positively has a continuous structural change.

As one preferable example, there may be mentioned one epitaxially grown at the corner portion of the grain. It is also effective to further increase the silver chloride content of the silver halide emulsion for the purpose of reducing the replenishment amount of the developing solution. In such a case, an almost pure silver chloride emulsion having a silver chloride content of 98 to 100 mol% is also preferably used.

First, a sensitometer (FWH type, manufactured by Fuji Film Co., Ltd., color temperature of light source: 3200K) manufactured by Fuji Film Co., Ltd. was used as Sample 101, and three-color separation exposure for sensitometry was applied. The exposure time at this time is 0.1 seconds. The exposure amount was set to 250 CMS. Using a paper processor for the sample that has been exposed to light, using a liquid having the following processing steps and processing liquid composition,
Color development processing was performed.

Further, in the same manner as in Use 101 except that the titanium oxide density in the support, the additives in the second layer, the fourth layer, the comparative dye I and the amount of gelatin added were changed as shown in Table 9 below. Samples 101 to 118 were produced. Here, Comparative Dye I was made into an aqueous solution containing 5% by weight of the compound, and each was added so as to have the coating amount shown in Table 9. The compound represented by the general formula (Sa) was vibrated and ball-mill dispersed by the following method. Water (21.7m
l) and 3 ml of a 5% by weight aqueous solution of sodium p-octylphenoxyethoxyethanesulfonate, 5% of p-octylphenoxypoly (polymerization degree 10) oxyethylene ether.
A 0.5% by weight aqueous solution and 0.5 g of a dye represented by the general formula (Sa) of the present invention are put in a 700 ml pot mill.
And zirconium oxide beads (diameter 1 mm, volume 500
ml) was added and the contents were dispersed for 2 hours. The vibrating ball mill used is a BO type manufactured by Central Processing Machine. The contents were taken out and added to 8 g of a 12.5 wt% gelatin aqueous solution, and the beads were filtered to obtain a dye gelatin dispersion. Sample 101 is also used for all the samples manufactured in this manner.
Color development processing was performed in the same exposure and processing steps as in.
The following evaluations were performed on all the samples obtained as described above. (White background coloration degree) In the above-treated sample, the cyan density (Dmin) of the uncolored portion was measured by X-Rite 310 (The X-Rite
The value of the difference (ΔDmin) with respect to Dmin of the sample 104 was used as a standard. In addition, the yellow density difference (ΔDmin) of the uncolored portion before and after dark storage at 80 ° C.-70% RH for 7 days was calculated for the above-treated sample.
The value was measured with the above X-Rite 310, and this value was used as a guide for coloring after storage under moist heat. (Sharpness) Here, a value called CTF was used. CTF represents the attenuation of the amplitude with respect to the spatial frequency as a square waveform, and here, the spatial frequency is 1 and 25 lines / m.
The value of CTF in m was shown. The larger this value, the higher the sharpness. The sample for CTF measurement was subjected to the same treatment as above by exposing the resolution test chart through a red filter. All the above results are shown in Table 9.

[0091]

[Table 9]

It can be seen from Table 9 that the ΔDmin after dark storage is improved by reducing the total gelatin coating amount as compared with the comparative sample 101 as in the comparative samples 102 to 104. However, the sharpness was poor and satisfactory photographic properties could not be obtained. Next, with respect to the comparative sample 104, the comparative samples 105 and 10 in which the addition amount of the comparative dye I was sequentially increased.
It can be seen that a sharpness of 6 improves. However, it can be seen that the non-coloring property of the white background of the uncolored part of the comparative sample 104 cannot be maintained. Further, regarding the comparative samples 107 and 108 in which the solid dispersion of the compound represented by the general formula (Sa) was added to the comparative sample 104, in addition to the sharpness not being sufficiently improved, It can be seen that the non-coloring property of the white background of the uncolored part cannot be maintained.

Similarly, comparing Comparative Samples 110 and 111 in which the density of titanium oxide in the water resistant resin layer on the side of the support on which the silver halide emulsion layer was coated was increased, Comparative Sample 104
Although the non-coloring property of the white background is maintained, the sharpness is still not at a satisfactory level. However, sample 112-
Looking at 114 and 116 to 118, it can be seen that the sharpness is remarkably improved in both the high frequency region and the low frequency region, and that the combination of the present invention makes it possible to obtain a photosensitive material having an excellent sharpness in the entire frequency region. In addition, at that time, it is also found that the non-coloring property of the white background is not deteriorated. Further, sample 1 of the present invention
On the other hand, comparing Sample 16 and Comparative Sample 115 in which the total gelatin coating amount was increased to 8.50 and 9.00 g / m ² , respectively, in Comparative Sample 115 in which the gelatin coating amount was 9.00 g / m ^2. It can be seen that the non-coloring property of the white background after storage under moist heat is inferior. That is, it is understood from the results in Table 9 that the combination of the present invention is the most excellent combination of the sharpness and the non-coloring property of the white background of the uncolored portion. On the other hand, sample 1
01 to 118 are exposed in the same manner as above, and the exposed samples are subjected to the same treatment steps and treatment composition solutions as above, respectively, and continuous treatment is carried out until the tank is replenished with twice the tank capacity of the color developing solution. Then, the developing solutions in the running equilibrium state were prepared. It was confirmed that the effects of the present invention were obtained even when the same test as above was performed using this paper treatment liquid.

Example 2 Samples 201 to 207 having the structure shown in Table 10 were prepared with respect to the sample 104 prepared in Example 1. Here, the AH2 layer and the hydrophilic colloid intermediate layer were applied between the support and the first layer in the following constitution so that the AH2 layer was located on the support side. Preparation of AH two-layer coating solution (colloidal silver-containing layer) 2 g of anhydrous sodium carbonate was added to 1000 g of 10% gelatin aqueous solution, and 500 ml of 10% silver nitrate aqueous solution was added thereto while keeping the temperature at 45 ° C, and 35 g of anhydrous sodium sulfite and 25
1000 ml of an aqueous solution containing g of hydroquinone was added over 10 minutes. After standing for 10 minutes, about 100 ml of 1N sulfuric acid was added to adjust the pH to 5.0. The obtained colloidal silver sol was poured into a cooling dish to cause sufficient gelation, then chopped into noodles, washed with cold water for 6 hours and sufficiently desalted. Preparation of coating solution for hydrophilic colloid intermediate layer 2000 ml of water was added to 1000 g of 10% gelatin aqueous solution, and 8 ml of 5% sodium dodecylbenzenesulfonate aqueous solution was added as a dispersant. All of these samples were exposed and treated in the same manner as in Example 1 to evaluate their sharpness and white background coloration. All the results are shown in Table 10.

[0095]

[Table 10]

Looking at Table 10, comparative sample 104 of Example 1
In contrast, an AH2 layer and a hydrophilic colloid intermediate layer are provided,
Comparative sample 2 with increased colloidal silver content in AH2 layer
From 01 and 202, it can be seen that in addition to the deterioration of the non-coloring property of the white background of the comparative sample 104, the sharpness is not at a sufficient level. However, looking at the samples 203, 204, 206 and 207, which are combinations of the present invention, it is found that not only excellent sharpness is obtained in the entire frequency region, but also the non-coloring property of the white background is maintained. In addition, the amount of gelatin applied to sample 204 is 9.0 g / m 2.
^It can be seen that the comparative sample 205 set to ² is inferior in the non-coloring property of the white background after dark storage. That is, it is understood from the results in Table 10 that the combination of the present invention is the most excellent combination of the sharpness and the non-coloring property of the white background of the uncolored portion. on the other hand,
The samples 201 to 207 were exposed to light in the same manner as above, and the exposed samples were treated with the same treatment steps and treatment compositions as above, respectively, and continuously treated until replenishing twice the tank capacity of the color developing solution. This was carried out to prepare a developing treatment liquid in a running equilibrium state. It was confirmed that the effects of the present invention were obtained even when the same test as above was performed using this paper treatment liquid.

Example 3 Samples 301 to 309 having the structure shown in Table 11 were prepared with respect to the sample 104 prepared in Example 1. A
The H1 layer was applied between the support and the first layer in the following constitution. Preparation of AH 1-layer coating liquid (white pigment-containing layer) An average particle size of 0.
400 g of 23 μm rutile titanium white pigment (Titanium White R780 manufactured by Ishihara Sangyo Co., Ltd.) and 4000 ml of water
Was added, and 8 ml of a 5% aqueous solution of sodium dodecylbenzenesulfonate was added as a dispersant, and ultrasonic irradiation dispersion was performed. All of these samples were exposed and treated in the same manner as in Example 1 to evaluate their sharpness and white background coloration. All the results are shown in Table 11.

[0098]

[Table 11]

Table 11 shows that the sharpness (particularly on the high frequency side) can be satisfied in Comparative Samples 301 to 303 in which the coating amount and the addition amount of the white pigment in the AH1 layer are adjusted with respect to Comparative Sample 104 shown in Example 1. You can see that you have not reached the level. However, Sample 304, which is the combination of the present invention,
From 309, it can be seen that excellent sharpness can be obtained in all frequency regions. At that time, it is understood that the non-coloring property of the white background is not adversely affected. That is, it can be seen from the results in Table 11 that the combination of the present invention is the most excellent combination. On the other hand, samples 301 to 309 were exposed to light in the same manner as described above, and the same processing steps and processing composition solutions as described above were used for the exposed samples, respectively, until the tank was filled with twice the tank capacity of the color developing solution. Carry out processing,
Each developing solution in a running equilibrium state was prepared.
It was confirmed that the effects of the present invention were obtained even when the same test as above was performed using this paper treatment liquid.

Example 4 Samples 401 to 409 prepared in the same manner as in Examples 2 and 3 so that the AH1 layer, the AH2 layer and the hydrophilic colloid intermediate layer were formed in order from the support side so as to have the constitution shown in Table 12.
The same treatment and evaluation as in Example 1 were performed.

[0101]

[Table 12]

The coating amount of the white pigment in the AH1 layer is 1.0 g.
/ M ² of the comparative samples 401 and 402 and the samples 403 and 404 of the present invention in which the coating amount of the white pigment in the AH1 layer is 3.0 g / m ² , the comparative samples 401 and 4 are compared.
It can be seen that increasing the coating amount of colloidal silver No. 02 slightly improves the absolute value of the sharpness and the spatial frequency dependence, but deteriorates the non-coloring property of the white background. However, looking at Samples 403 to 409, which are the combinations of the present invention, it can be seen that not only the best sharpness is obtained in the entire frequency region, but also the non-coloring property of the white background is maintained. That is,
From the results in Table 12, it is understood that the combination of the present invention is the most excellent combination of the sharpness, the non-coloring property of the white background of the uncolored portion and the storage stability of the light-sensitive material. On the other hand, samples 401 to 4
09 is exposed to light in the same manner as above, and the exposed sample is subjected to the same processing steps and processing composition solutions as above, respectively, and continuously processed until the tank capacity of the color developing solution is replenished twice. Each developing solution in a running equilibrium state was prepared. It was confirmed that the effects of the present invention were obtained even when the same test as above was performed using this paper treatment liquid.
